This version addresses several bug fixes. Including two critical bugs concerning data storage for the date and grid components. If using any 2.1 version of the module, upgrading immediately is recommended.
The big change is that now, when the Views module is enabled, the workflow module will provide two default views. One shows an overview of the states and nodes are in (filterable by state and by node type) and the other provides a view of pending state changes for nodes that have state changes scheduled using the "scheduled state change" option on the workflow tab.
